INCINERATOB.

Specification of Letters Patent.

Patented Aug. 4, 1914.

To all whom it may concern.

Be itr known that I, JAMES B. Rrcna'rrs, a citizen of the United States, residing at New York, borough of Manhattan, State of New York, have invented a certain new and useful Improvement 1n Incinerators, of

which the following is a specification, reference bein nying drawmgs. This invention relates to incinerators to be used for the `storage and destruction of any matter that it is desired to destroy by tire, but it 'is especially intended for application to the construction of incinerators used for the ldestruction of garbage and other combustible refuse matter.

The-present invention contains improve` ments .upon the device shown in my prior application fled'Dec. 14,1911, Serial No. 665,611. In oneyform of construction shown in said prior ap lication the burner illus trated was a gas urner and in the form of grate construction shown in connection with the burne. in said application the gas must pass through grate bars before impinging upon the matter to be destroyed in thc combustion chamber, and in so doing much of its power is w'asted before coming in contact I pilot light.

with thematter to be consumed. On ,account of the excessive heat on the grate liars the life'of thesame is greatly curtailed.

One object of the-present invention is to construct the grate with openings so located with relationto the openings in the gas burner that the gas flame will pass through without'coming in contact with the grate itself and impinge itself immediately upon the matter to be consumed.

Another object of the invention is to provide a meansy whereby the gas burner may` be lighted from the outside of the machine without `resorting to the usual method of a The invention will be fully understood from the following description taken in connection with the accompanying drawings and the novelfeatures will'be pointed out and clearly defined in the claims at the close of the specification'.

lIn the drawings: Figure 1 is a vertical settion 'of a device embodying the invention.

Fig. 2 is a cross section on line 9,-2 of Fig.

had therein to the accompa.

tion chamber for the reception of the garbage or other refuse, attire chamber beneath the primary combustion chamber, a second ary combustion chamber located above the primary combustion chamber Within which the gases arising from the matter in the primary combustion chamber are destroyed, fire `duets leadin around outside o the primary combustion chamber into the secondary combustion chamber and preferably also comprisesa detlector and auxiliary burner.

Referring now to the drawings, theV pri` mary combustion chamber has side walls 1, and a dumping grate forming the bottom of the combustion chamber. This dumping grate is preferably formed in two companion sections, each section being of an ular shape and formed with a shaft 3 at the ]unc tion of the two wing ortions 4, 5 by which it is mounted in its earings. Each grate section has a wing portion '4 which extends from the shaft 3 preferably at an upward inclination toward the wall and on which the matter to be consumed mainly rests. l t is also formed with a wing portion 5 which from the fire chamber extends at an upward inclination toward v thc'middle of the combustion chamber. The two wing portions 4, 5 of tho two grate sections in the operative position thereof ap? proach to a meeting line above at their u per edges, and form a hood outside of tie burner itself.

It is to be observed that each grate meinber or section is of such form in cross section as to produce a pocket or recess in the upper side thereof, and when the structure is in use the pocket is lillcd constantly with a limited amount of the refuse to be consumed. It will be noted, furthermore, that in the operative position of the grate meinbers, as shown in Fig. 1, the wings 5 thereof extend upwardly and inwardly toward eacl` other, the general direction ofuch wings being on converging lines. This construction and arrangement of the grate members performs several important functions; first, the wings in the operative position of the grate members produce a hood which inrases the upper side of the burner, as heretofore mentioned; second, the mass of solid material at the ,lower part of the primary combustion chamber i's divided b the converging wings, and, third, the iippositely v inclined wings direct the solidlnuterial in lltl ` two directions away from and into the pockets As a result, the pockets of said burner.

l formed with a the central vertical part of the primary combustion chamber members.

the respective grate grate members are charged or filled with relatively small quantity of the refuse, and

the flames from the burner are brought into `contact with such small quantities of refuse, thus facilitating the incineration thereof.

The burner 6 extends through and is formed with a series lon each' side of the burner, beingso located that the gas sent out in a lateral direction,

The wing portion horizontal.

the machine of openings 7 these openings flame will be substantially 5 of each grate section is formedwith a lower or base portion 8, which extends upward in a more nearly vertical direction than the upper por` i tion of the wing. This base portion 8 is formed with large openings 2 so located that the gas flame will,

pass

from' the burner directly through said'openings and impinge upon the matterl to upon the wing portion pocket of the gratev portions 5 are part ofthe wing be burned which rests 4,' and within the The upper formed as member.

a series of bars with 'spaces between them through which the ashes may drop,

through which the deflected heat will pass up into the ashes may drop. above the top of the the garbage immediately above the The wing portion with a series of openings .4 is also formed 9 through which A hood 10 is provided burner 6 to protect the same from ashes falling from the grate. The sidewalls 1 of the combustion chamber are formed at the lower ends with inwardly sloping flange portions 11 which project slightly over the wing` portions 4 of' the so located as grate 4so that any drippings in the combustion chamber, will be carried down and fall onto the grate wing 4 and follow the slope then drop to the trough 12 to receive the drippings. rl `hese drippings will then be evaporated by the deflected heat.

' A casing 13 surrounds, the combustion chamber and extends to some distance above and below this chamber.

In the lower part of the casing 13 is the lire chamber 14, within which lis located the burner G described.

previously The primary combustion chamber is havingfan opening 16 and the'casing 13 which extends above the primary combustion chamber is formed with a top 17 having the smoke flue. primary combustion of the easing isthe open term the secondary an opening 18 leading to Between the top of the chamber and the top space 19 which I combustion chamber a nd in this secondary combustion chamber there is preferably located a ch ambered detlector 20 which contains an auxiliary burner 2 1.

. and there is also an opening front `casing into and' the burner for supporting i tray.

of the primary combustion chamber into the lire ducts 23 between the primary combus tion chamber and the casing, and detlectors 27 also' project from the casing 13 into the The wings 4 ofthe grate are lire ducts.

'timed with flanges 28 at also preferably f their outer ends whfich extend at a doWn-` ward lnolination for the purpose or' retarding the free passage of the burning gases from the re chamber through the fire ducts.

In' order to light the burner without the aid of a pilot light or gaining access to the interior of themachin'ethe burner 6 is exthe casing to the outside thereof and is Jformed with per orations 29 in that portion which is between the combustion chamber and the front A sleeve O'surrounds that portion burner between the front casing and being-ot larger diameter-.than thevburner, so that there is a space between the bui-ner and the said sleeve, 31 through the of the When it is desired to light the. burner it' the coclristurned` to turn on the gas a lighted match may be applied to the opening 31 at the.outside',.and suilicient gas will escape through the openings 29 so that it will be immediately ignited bythe match, and the gas being thus ignited will follow through the end of said sleeve.'

and ignite the gas in the burner Within the fire chamber.

From the 'foregoing description l conjunction with the drawings, it will be noted that my invjention embodied a dump ing grate adapted tosubsftantially incase fthe burner, for the purpose of supporting the material to be consumed in such relation to the burner that the ,llame emanating from said burner will come into direct contact with the material to vbe consumed. As

shown, said grate is composed of two sections, said sections having upwardly convergingunembers yadapted) to extend` over the material. The grate sections are inoyable for the purpose oidnmping. the uncornsun'ied material, said grate operating to dump,tlie material away from the burner, wherebylodgment of the unconsumed materialy upon the burner is precluded, so that the flame openings of the burner will not be `obstructed by the material. Furthermore, the evaporating tray 12 is in` such relation to the grate that liquid froml the `materiahresting upon the grate will/be drained oi' flow by gravity into said The tray is positioned bel-ow, and in close relation to, the burner so that the heat from the burner will evaporate the liquid contents of the tray. Said cvaporating tray is Inounted'to dump in unison with tbe grate for the purpose of discharging any solid material which may fall by gravity intc the tray. tray yis dumped simultataken in i embodying two wings :neously with the duiiping movement of the grate, and the unconsumed material from both the tray and the grate may be discharged into a receptable positioned in .the lower part of the incinerator.
